Variety of Hydrangea plant named ‘Stramini’

ABSTRACT

A new and distinct  Hydrangea  plant having multicolored flowers and strong stems.

Botanical classification: Hydrangea macrophylla.

Varietal denomination: ‘STRAMINI’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Hydrangeaplant known by the varietal name ‘Stramini’. The new variety wasdiscovered in 2006 in a planned breeding program in Harderwijk, TheNetherlands. The purpose of the breeding program was to developHydrangeas with improved green-like flower colors. The new variety isthe result of a cross between breeding selection Seedling 1012 (femaleparent, unpatented) and Seedling HY 2586 (male parent, unpatented). Thecompact nature of ‘Stramini’ is similar to its female parent, but itdiffers from Seedling 1012 in flower color. The flower color of‘Stramini’ is similar to its male parent, but it differs from SeedlingHY 2586 in leaf shape. Further, ‘Stramini’ exhibits greener coloredflowers than Hydrangea plant ‘Elbtal’ (upatented). The new variety wasfirst asexually reproduced in 2007 via propagation by cuttings inHarderwijk, The Netherlands. The new variety has been trial and fieldtested in Harderwijk, The Netherlands and has been found to retain itsdistinctive characteristics and remain true to type through successivepropagations.

The following traits distinguish ‘Stramini’ as a new and distinctcultivar from other Hydrangea varieties known to the breeder:

-   -   1. Multi colored flowers with a greenish hue; and    -   2. Strong stems.

DESCRIPTION OF THE DRAWINGS

The accompanying photographic drawings illustrate the new variety, withthe color being as nearly true as is possible with color illustrationsof this type:

FIG. 1 is photograph of an entire plant of the new variety; and

FIG. 2 is another photograph of the same plant of the new variety ofFIG. 1, whereby color differences are due to differences in theflowering stage of the plant.

DESCRIPTION OF THE PLANT

The following detailed description sets forth characteristics of the newcultivar. The plants were grown in 15 cm. pots, 8 per m², in ordinarypotting soil with granulated fertilizers at a pH of 6.0. The plants weretwo years old when described. Measurements and color readings of theplants were taken in Harderwijk, The Netherlands under natural light.Color references are primarily to the HTML Color Chart.
